In JAPJI SAHIB PAURI 30, GURU JI CLEARLY SAYS
eaekaa maaee jugath viaaee thin chaelae paravaan |
The One Divine Mother conceived and gave birth to the three deities.
eik sansaaree eik bhanddaaree eik laaeae dheebaan |
One, the Creator of the World; One, the Sustainer; and One, the Destroyer.
jiv this bhaavai thivai chalaavai jiv hovai furamaan |
He makes things happen according to the Pleasure of His Will. Such is His Celestial Order.
ouhu vaekhai ounaa nadhar n aavai bahuthaa eaehu viddaan |
He watches over all, but none see Him. How wonderful this is!
aadhaes thisai aadhaes |
I bow to Him, I humbly bow.
aadh aneel anaadh anaahath jug jug eaeko vaes |30|
The Primal One, the Pure Light, without beginning, without end. Throughout all the ages, He is One and the Same. ||30||
according to hindu myth dere are three gods which are born from some mata (kali aur durga) but GURU JI clearly states dat everything is in WAHEGURU JIS HUKAM.
SAHIB SRI GURU GOBIND SINGH JI MAHARAAJ in CHAUPAI SAHIB SAYS
mehaadhaev ko kehath sadhaa siv |nirankaar kaa cheenath nehi bhiv |6|
He continues calling Shiva as the Eternal God. But he does not know the secrets of the Formless God.
so it is clear mahesh was just a mahadev not SHIV JI (AKALPURAKH JI)
bhul chuk maaf
Waheguru ji ka khalsa
Waheguru ji ki fateh
